There was immense diversity in how gendered the nations were; in the ones that had the strictest gender roles, there were often additional gender roles that could be taken up. They were found less in communities which had less strict gender roles.
My understanding was that, in many of these communities, there were no gender 'roles' as such. All positions were open to all, and weren't viewed as the job of a particular gender. I am aware that some believed that particular genders had higher spiritual inclination, though.
The idea of gender roles, to many of the communities, was introduced by invaders. However, they did have a multitude of genders in each community though the names were often different.
Been a long time since I've studied this though, so open to correction!
But how would they know that what they’re feeling is what folk of the opposite sex feels - it just doesn’t make sense. A male feeling out of sorts with maleness, with their body, being desperately unhappy - none of this means they are a woman instead.
This is the sort of question you should be asking an actual trans person who is open to receiving these sorts of questions, not me.
I'm not trans. I don't know.
Then why the constant insistence that people who don't identify as trans (or non-binary, which most non-binary people I know, or know of, see as a type of trans) must accept the label "cis"?
I'm sorry, I've never heard someone insist that somebody who identifies as elsewhere or outside of the gender spectrum refer to themselves as cisgender.
Is it like when dickheads people say that the gender is made up and they should just go by the pronouns associated with their sex?
